Plant Growth System 60

Most aquatic plants depend on CO2 for survival. However, this is not the case for algae, which can thrive with very minimal CO2 supply. Therefore, without adequate CO2 fertilization, the plants in your aquarium will likely suffer while algae takes over and damages the delicate balance of your aquatic ecosystem. The Tropica Plant Growth System 60 is a simple and practical way to provide your aquatic plants with an adequate supply of CO2 so that they can grow and thrive and help keep algae at bay. Each cylinder contains approximately 169 fluid ounces (5000 ml) of CO2 and should last for over 2 months in a 5.28 gallon (20 L) tank. However, the Tropica Plant Growth System 60 can also be used in smaller doses for starter sets and small aquarium setups. Refill CO2 cylinders are sold separately. Use the table below as a guideline to determine recommended CO2 dosages for your tank.
